1. A method in an access network comprising:
- within a system bandwidth, assigning a first time-frequency resource for transmissions from a first UE using a grant-based access scheme based on a minimum transmit unit (TU) size constraint of the grant-based access scheme and assigning a second time-frequency resource for transmissions of a second UE using a grant-free access scheme based on a minimum TU size constraint for the grant-free access scheme, the minimum TU size constraint for the grant-free access scheme requiring a different time duration than the minimum TU size constraint for the grant-based access scheme;
receiving a first transmission from the first UE over the first time-frequency resource in accordance with the grant-based access scheme; and
receiving a second transmission from the second UE over the second time-frequency resource in accordance with the grant-free access scheme.

Abstract
Systems and methods for flexible channelization are provided. Different TU sizes are used for transmissions by different UEs. The different UEs may use different access schemes, and may transmit using time frequency resources that at least partially overlap.

18. An apparatus comprising:
a processor; and
a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to;within a system bandwidth, assign a first time-frequency resource for transmissions from a first UE using a grant-based access scheme based on a minimum transmit unit (TU) size constraint of the grant-based access scheme and assigning a second time-frequency resource for transmissions of a second UE using a grant-free access scheme based on a minimum TU size constraint for the grant-free access scheme, the minimum TU size constraint for the grant-free access scheme requiring a different time duration than the minimum TU size constraint for the grant-based access scheme; receive a first transmission from the first UE over the first time-frequency resource in accordance with the grant-based access scheme; and receive a second transmission from the second UE over the second time-frequency resource in accordance with the grant-free access scheme. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
